PRECAUTION
1. PRECAUTION OF HEADLIGHT BULB REPLACEMENT
(a) When any defects such as deformation, crack, dent, chipping, etc. are identified on the discharge
headlight (especially, on the light control ECU), replace it with a new one.
(b) Even if the operation seems to be normal, the fail±safe function may be defective.
(c) Be careful not to scratch on drop bulbs of the discharge headlamp and halogen bulbs (for headlamp
and fog lamp), as they have pressurized gas inside and can be easily broken.
(d) Touching the HV socket of the discharge headlight with the headlight dimmer switch ON could gener-
ate momentary high voltage of 20,000 V and lead to a serious injury.
(e) Never connect a tester to the high voltage socket of the discharge headlight for measurement, as this
leads to a serious injury because of high voltage.
(f) When performing operation related to the discharge headlight, keep it away from water including rain,
turn off the light control switch, and disconnect the battery terminal and the connector of the light control
ECU in advance to avoid electric shock.
(g) When performing operation related to the discharge headlight, start it after assembling is completed
and never turn the lights on without a bulb installed.
(h) Do not turn the discharge headlight on using another power source except vehicle's.
